Our Products

CASWELL FIRESAFE® non-coated fire resisting ductwork systems are classed as Passive Fire Protection and have achieved verified fire resistance to protect against the spread of fire from one compartment to another.
CASWELL FIRESAFE® provides this assurance with their Passive Fire Protection products; without the need for enclosures, spray coatings, fabric coverings or an excess of fire dampers.

The CASWELL FIRESAFE® system was first developed and tested in the early 2000’s in accordance with British Standard BS476 Part 24 (1987).
Since then the introduction of harmonised European Standards has seen further range development and testing investment in order to meet UK and European legislation including CE marking.

CASWELL FIRESAFE® products are also used for smoke evacuation control; in which case passive fire systems must operate under fire conditions. It can be used to quickly and safely exhaust smoke and, as an integral part of a pressurised system, prevent it from entering protected fire escape routes, specifically stairwells, to maximise valuable escape time. Ducts which penetrate compartment walls and floors must achieve the same fire resistance as the compartments through which they pass.

CASWELL FIRESAFE® product is available in two fully tested and certified ranges:
– BS 476:Part 24 up to 240 minutes
– EN 1366-1 & 8 up to 120 minutes
